  • Connecting mechanism of connector
    Patent number: 6488521
    Abstract: It is an object to reduce a load given to connectors when the connectors are connected with each other in a connection mechanism composed of the main body side connector 20 and the base unit side connector 10 in which contact terminals of both the connectors are contacted with each other when the connectors are moved in the mutual direction. The base unit side contact terminal 12 is movably attached to the housing 11 of the base unit 10 so that the base unit side contact terminal 12 can be located at a non-contact position with respect to the contact terminal 22 of the main body side connector 20 at the first stage of engagement between the connectors 10, 20 and so that the base unit side contact terminal 12 can be located at a contact position with respect to the main body side connector 20 at the latter stage of engagement between the connectors 10, 20.
